AFAIK, Sonys PS2 recognize only about 139 GB on your hard drive, no matter how bigger it is than those 139 GB ...

134 GB I think, in fact, but the latest version of HDAdvance (from 2.0 and up) lets you use up to 200 GB in size.

HDLoader was discontinued because it said it was supported by Sony, which it wasn't, and Sony didn't like it, HDAdvance is made by the same guys, but this time, no copyrights.

The PS2 HD can only be used as a memcard with games that support this feature.

As for reading divx, yeah, ArchIBald is right, don't do it, it will just kill your lens.

AFAIK, no, I've searched for such an app, and the only thing I found is a tool to backup your save on your PC through the LAN.
